Aceto is the Italian word for vinegar. Italian vinegars are usually made from wine, unlike in other countries where vinegars are sometimes made from coconut sap, or palm sap. The best Italian aceto is the syrupy aceto balsamico tradizionale (traditional balsamic vinegar), only made once in Emilia-Romagna Region of Italy, now made elsewhere in varying degrees of quality. Otherwise a simple red wine vinegar is used to dress salads and marinate fish.
